We performed a comparison between IBM PowerVM and Nutanix Cloud Infrastructure (NCI) based on real PeerSpot user reviews.
Find out what your peers are saying about Proxmox, VMware, Microsoft and others in Server Virtualization Software."IBM PowerVM has the highest clock speed."
"Active Memory Sharing dynamically reallocates memory of running partitions based on changing workload demands. The memory for the pool is carved out from Physical memory and is made logical memory. The said memory is not available to be assigned to partitions as dedicated memory. A min, max and desired as well as weight is assigned to the memory of each lpar to help hypervisor make a decision in case a condition where priority is to be given to a certain lapr to use the memory form shared pool."
"The feature that I like most is the versatility."
"You can increase resources with it automatically."
"It is a complete solution."
"The product never fails to work and is very stable in general. Stability-wise, I rate the solution a ten out of ten."
"Technical support is great."
"We always recommend PowerVM to our customers; it is better than most solutions."
"It supports multi-cloud integration that includes AWS, Google, and Azure."
"The most valuable feature I have found to be the Acropolis Hypervisor (AHV)."
"The most valuable features are the user-friendly dashboard and that we don't need to move resources manually when adding new nodes into running clusters."
"We really love the Lifecycle manager and one-click upgrades."
"The most valuable feature would be the ease of deployment. That is the most significant feature for me because I've worked with multiple vendors and it's always been very complicated to install the software and get everything running."
"This operating system offers stability. Setup is straightforward."
"Nutanix Acropolis AOS is stable. We didn't receive any concerns regarding any problems, The customers have no concerns about the reliability."
"The product is easy to manage."
"The licensing could be better."
"SRM for site recovery is a feature that should be included."
"The performance should be improved."
"Automatic LPM is an area that is currently not available in IBM PowerVM, and it is a feature I want to see in the product's future releases."
"I don't know whether this has been trialed already, but IBM should give us an alert when we reach seven or eight failovers so that we can automatically switch it to manual mode. That would be great because if we cross the 10-day licensing limit, we have to pay a hefty license cost to Oracle. If IBM could view that feature, it would be helpful in license compliance."
"The product's pricing could be less expensive compared to other competitors."
"The interface is not user-friendly in places, so it could use some improvement."
"IBM PowerVM does not integrate with Microsoft."
"One of the improvements I would like to have is related to naming. It is getting confusing because they are using three-letter acronyms, which are more or less misleading. What I do not like is that they changed names and reused names. They had a meaning in the past and they are still using the names for something similar."
"The software-defined networking should be improved. It is quite substandard as compared to the VMware variant. The software-defined networking is quite limited, and we usually use other products to do that. We're aware that Nutanix is working on that and will be coming out with better solutions, and we can't wait because to do a fully software-defined architecture, the abstraction layer needs not only software-defined storage, which you have, but also the software-defined networking piece."
"Limits on increasing space with the inability to have or attach external storage."
"I would like to see them utilize the spare storage that they use as a redundant space. I feel that now a lot of resources are wasted just for standby purposes because we are using data protection. Instead of utilizing those resources only when something happens, they can have an alternative so that we can utilize these resources all the time."
"As Nutanix Acropolis AOS is on the expensive side, one of its areas for improvement is the price. It would also be better if it can be integrated with other cloud providers, because currently, it's only for private cloud deployment."
"It is a CentOS-based operating system, but CentOS releases security patches almost every week or every other week. However, Nutanix releases their upgrade at three or four month intervals. According to my organization's SLA, if a critical patch is released during that time, then I need to implement the patches within 30 days. If it is a standard patch, then I need to patch it within 60 days. Since that is my SLA, I cannot meet my SLA for security because Nutanix will not release the upgrade within these 30 days. Between the critical patch release and the Nutanix release, my customers say they are vulnerable and I am accepting the risk while the SLA is breached."
"In terms of what I would like to see improved, I would say the life cycle management. I don't know if it is because they changed to an LCM from the previous way of upgrading the hardware or software but sometimes it feels that it needs a wizard that says, "Check this, check this," telling you your options. The only thing that's a bit frustrating for me is the life cycle management interface. That's the only thing on the entire system that frustrates me."
"As far as what could be improved, they have some built-in backup functions already, but any built-in isolation features like vision security features and free LAN features become a security concern."
